IMPROVEMENT INV HEEL-STIFFENERS.

Specification forming part of Letters Patent No. 134,736, dated January 14, 1873.

To all whom it may concern:

Be it known that I, LUTHER C. GROWRLL,

of Boston, in the county of Suffolk and State` of Massachusetts, have invented a new and Improved HeelStiffener; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms a part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

made of rubber or a similar compound are ofV similar form in blank, and then pressed into such shape as will conform withvthat of the heel of the boot or shoe into which it is inserted.

My invention has reference to the production of a heel-stitfener which shall be of such shape as will require the least amount of material, and is efficient for supporting the shoe where the most rigidity is required, enables blanks of one size to fit boots and shoes of dierent sizes, and is the most convenient for packing and transporting, is readily applied, and admits of bein g readily and securely fastened in position with the least possible manipulation, and allows the use of metal in its construction, which has heretofore been too expensive on acconntof the waste and amount of material necessary to construct, it of the usual form.

The drawing represents a heel-stiii'ener or blank embodying my invention.-

Figure l represents the shape into which a sheet of metal or other suitable material may be cut, u.and produce heel-stii'eners of a desirable form, without waste of material. The blanks of the form shown, having the two pro-- jections B B upon the upper edge and the three projections A A Avupon the opposite or lower edge, the middle projection A being slit, .as shown, are inserted between the upper and the lining of the shoe, the upper or the edge having the projections B. B being pressed between the upper and the lining until the sole of the shoe is on a line with the base of the lower edge, leaving but the three projections AA A extending beyond the sole. These projections are then bent in upon the sole and permanently secured in position in securing the heel and sole to the shoe. When in shape in the shoe my invention assumes the form represented by Fig. 2.

Having thus fully described my invention,

whatI claim as new, and desire to secure by
